Sages and naturalists frown at the common name given to these strange creatures by the small folk, but sometimes the silliest nicknames for creatures, places and people persevere in the minds of many. “Purifiers”, “Pond Jellies”, “Breath-Stealers”, “Lung-Ticklers” and “River Butterflies” are much less commonly heard appellations for these life forms. Wet Faeries are basically (and simply) a species of fist-sized, fresh-water jellyfish. Several traits steer them toward the peculiar category however. Firstly, Wet Faeries are nearly invisible in the water, much like their marine cousins but even more so. One can swim in a river swarming with these critters and not even notice their presence. Secondly, they possess the unique ability to clean and purify whatever body of water they inhabit. They do this via some sort of biological filtration process, sucking in all toxins present in the water, and releasing it back in its purest form. Needless to say, they are both a blessing and a curse to whichever folk dwell beside the rivers and lakes Wet Faeries inhabit. On one hand, no purer water can be found anywhere than a Wet Faerie lake or pond, and yet, in “pure” water “life” tends in fact to die out, lacking the needed nutrients to prosper. Thirdly, their “sting” is (unfortunately) virulently poisonous to all mammalians. Wet Faeries are loathe to sting anyone or anything, using their barbed fronds as a last line of defense, but if stung, most swimmers will suffer respiratory arrest, and die within minutes, usually drowning before they can make it back to shore.
Alchemists, druids, and less savory characters have studied these creatures over the years, and have predictably found all the ways Wet Faeries could be exploited. Morbidly humorous, some bards find it, that the Poisoners and Assassins Guilds as well as the Healer’s Union, all prize these creatures. The assassins use the extracted venom in obvious fashion, while the priests and healers use the still-living jelly-fish to sterilize other poison potions and to cure those already poisoned on death’s door.
It is known that a certain Earl Von Trumble keeps his vast castle moat stocked with Wet Faeries, the waters so clear that every bone of every one of his past enemies can be clearly seen on the bottom, twenty two feet below.
These rare, fist-sized spiders do not make webs, but rather excrete secretions which harden upon contact with air. These "droppings" resemble barley-sized spider eggs, or even lustrous pearls, once the slime coating them, dries up. In fact, dried Pearl Spider "drops" are indistinguishable from the marine varieties produced by mollusks, and hence of identical value on the open market!
Several centuries ago, they were studied by naturalists, and several observations were made. Firstly, was that these spiders "lay" these pearls for no apparent or discernible "natural" reason, and secondly, the naturalists had discovered that the more these spiders ate or were fed--and they were true omnivores--the larger the spider pearls came out.
A cottage industry began. Enterprising merchants hunted and collected these creatures across the lands, erecting spider-farms for the manufacture of Spider Pearls. It wasn't long before someone got the idea to force-feed the spiders, ala foie gras geese, and soon, the fattened spiders began pooping out pearls of great size! (relatively speaking). The regular pearl market came to disarray, and prices and value fluctuated wildly.

While traveling trough farm land the PCs come upon a merchant sitting on a wrecked wagon without a mule attached to it, hid face burrowed in his hands. He explains that he was robbed by petty goblins, unable to defend himself he had retreated. He asks the PCs to help him retrieve the mule before the goblins roast it, as a reward they may keep his goods. How hard can it be?
